To (z/Z whom it may concern.

Be it known that. l, James R. FLnnixo, a citizen of ti e United rfitates, and a resident of Scranton, in the county of Lacliawanna and :State of Pennsylvanian have invented a new and improved Journal liearin elf which the following is a tull clear, and exact description.

.fiinong the principal objects for which the present invention designed are: To provide selt-alined bearing boxes and supports tlnirelhr constructed and arranged to be readily removed from the car and axle for repair or replacement: to provide a simple, ecoiuuaical and ellirient bearing box for ininingxars and similar Vehicles; and to provide a hanger and bearing box removahly supported thereby, constructed and arranged with reference to the avoidance of for machine-Work when assembling said hearing and hanger with the axle of a wheel.

Reference is to be had to the accompanying drawings tor-mine a part of this specification, in .which similar characters of reference indicate corresponding parts in all the views, and in'which- Figure 1 is a. side view of a bearing construeied and a ranged in. accordance with the present invention, the axle of a. vehicle seen in conjiumtion therewitl'i being shown in section; 2 a. bottom plan View, partly in section, of the bearing constructed and arranged in accorda ice with too present invention. the section being talcen on the line 2 -2 in Fig. 1; and Fig. 3 is a vertical section taken on the line 3 in Fi 1.

.-\s seen in the accoinpa ying drawings,

the axle A is mounted in a hearing box S.

The box 8 is shown pri'ivided with a triction-reiiluciiur hearing formed ol'- rollers B. Any suitable form of friction-redaction hearing" may be employed as a. substitute for that shown, the-character of bearing eniployed being optional.

As seen in tho aceompanyingdrawings, the box 8 is formed independent of the hanger in the bracket sides at-f), with which it is provided. In practice. the axle A may be independently equipped with the bearing boxes 8 and the bearing rollers B contained herein. To hold the bearing rollers B in position within the box 8 I have. formed at one end of the said box the closure end 10, and at the other end a slot to hold the ring cover 11. The ring cover 11 is perforated, is theclosuro end 10, to pass the axle Jr. The closure end 10 receives the tlnust of the hub of the wheel C. fxs seenin the drawings, the box 8 is crowned lengthwise. The extent of the curvature-of the crown is cylindrical and tapers toward its ends, and as shown in the drawings, is for purpose of illustration, exaggerated. The surface of the box 8 bears upon the base-plate 13 from which the brackets 9, 9 are extended. the preferred form of base-plate 18, the same is provided with a boss ll, spherical in shape to rock on the said box 8 in a manner similar to that of a universal joint.

The brackets 9, 9, as indicated serve to support the box 8 when the body of the car. is lifted to lift the carrying wl'ieels thereof. For this purpose, the lower end of each the brackets is provided with a groove l The grooves 15 are shaped to receive elongated ear tabs 16 extended from the Side of the box 8 at the longitudinal center and midwag. between the ends thereof. The grooves 15 are open at one end, and at the other end are closed. The side walls of the grooves 15 are straight, while the top and bottom sides and the outer edges of the tabs 16 are rounded or crowned, as seen best in Figs. 1 and 2 of the. drawings.

l5 enuiloying a cylindrical bearing box and providing it with car tabs or lugsarrange as described, the box can be inverted or reversed when one side becomes worn, thereby prolonging the life or the said box and by curving or rounding the edges of the ear tabs or lugs, a rol ring joint is formed in the. grooves of: the brackets, so that break.- ngre is rt-duced to a minimum and the noise inci -ent to the bearing separating from the base plate prevented.

By employing hangers constructed and arran. ed as shown, the need of the usnal bracnio: collar on the axle is dispensed with. By this construction the lateral axle thrust received on the tabs 16. and closed end of the hanger brackets 9/ The end thrust of the hangers on the boxes 9 is imparted initially to-ihe tabs 16. By rounding: the surfaces 01 the said tabs any disadjnstment of the axles A is compensated for to avoid imposing on'the boxes 8 a cramping or grinding strain. It will thus be seen by reference to the acconu'mnyin drawings and to the foregoing descriptioin that each part t -*-i -a" Patented Uri 4,191.5.

it a

of the box 8 and bearing members thereon is longitudinal center rounded Where the same is liable to contact with the hanger or any part thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

A journal bearing, comprising a base plate provided with two spaced depending brackets, each having on its inner face at the lower'end a groove leading out through one end of the bracket and terminating short of the other end of said bracket, said base plate being provided between the brackets with a spherical boss forming a bearing, and a cylindrical bearing box tapering toward its endsand provided on opposite sides at its and midway between the ends with elongated lugs having curved outer edges and fitting in the grooves of the brackets, whereby the bearing may be inverted and will be held so as to be free to rock Without noise and danger of breakage incident. to the separation of the bearing and base plate.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
